EYEGLASS PAD CONSTRUCTION Filed Dec. 16, .1959

INVENTOR.

Patented July 8, 1941 EYEGLASS PAD CONSTRUCTION 4 Claims.

This invention relates to an eyeglass construction, and more particularly to an arrangement of nose pad and structure for mounting it on an eyeglass frame.

A further object is to provide a simple and practical construction whereby a nose pad can be readily removed from the frame and a new pad assembled, thus effecting a substantial saving by eliminating the necessity of discarding the frame when a pad is injured and requires replacement.

A further object of the invention is to provide an arrangement whereby a nose pad may be quickly and securely fastened on a frame by the operator, and can be readily removed if it is desired to reverse the position of the pads.

A further object of the invention is to provide means for securing the pad to the frame, comprising a bifurcated structure forming a pair of prongs supported by a base plate part which is encased in the material of the pad, each of said prongs extending from said base plate in a manner which permits of their separation practically their entire length in the act of fastening the pad to the arm element of the frame.

By reason of this construction the prongs may be spread apart a further distance when the opening in the arm in which the prongs rest, become worn and cause a loose connection by reason of which the pad changes its position in the arm and requires adjustment.

My invention therefore is directed to the means for coupling the pad to the arm of the frame which supports the eyeglasses.

Referring to the drawing which forms a part of the specification:

Fig. 1 is a View of a pair of eyeglasses mounted in a frame and disclosing the arms which support the pads mounted thereon.

Fig. 2 is a view of an arm with a pad thereon.

Fig. 3 is a side view of a thin plate stamped from a sheet of soft metal, and further illustrated in Figure 4.

Fig. 4 illustrates the preferred form of stamping which is afterward bent to the required form for use.

Fig. 5 is a cross sectional view of a pad construction embodying my invention.

Fig, 6 is a plan view of one side of the pad in which the dotted lines indicate the form of the metal fastening means encased in the pad.

Fig. 7 is a sectional view taken on line 1-l of Figure 6.

The fact that both of the pads are made alike, a description of one together with the support ing arm will be sufficient to make the invention clear to those skilled in the art to which this invention pertains.

l0-,- indicates the frame portion of the device comprising the arm I l--- which is provided with a rectangular opening of the usual dimensions.

The edges of said opening are thin and become worn to a degree which requires repair.

|2 indicates a plate of soft metal consisting of a base portion I 2 and two members I 3l 3- respectively which are bent back upon the base portion'and then ofiset therefrom to provide two prongs, as illustrated in Figures 6, and '7.

The base plate portion l2' is embedded in the body of the pad in the usual manner well known to the art, and is illustrated in Figures 2, 5, 6, and 7.

If desired the extension portions of the base plate indicated by M- and l5- may be reduced in length to that corresponding to the width of the members l3, if desired, to save the cost of the metal and increased cost of the stamping operation required to provide the full plate shown, but the metal part could be made from a strip of metal of uniform width, which when bent upon itself and then outwardly at a right angle to the surface of the base, would provide a construction suitable for proper use.

After the members are passed thru the opening in the arm H- they are forced apart and their ends bent to an offset position as illustrated in Figure 2, to secure the pad to the arm, and in performing this operation the prongs separate from their point of junction indicated by l6 in Figure 7 Therefore, when the orifice in the arm becomes worn, the elements l3- may be spread apart a further distance to take up the worn space in the arm, and thus prolong the life of the pad or arm, or both of the same.

The construction is such that the pad may be easily and quickly secured to the arm or detached therefrom without the use of special tools designed for the purpose.

Having thus described my invention I claim as new:

1. A pad construction for eyeglasses comprising a plastic body pad portion, a non-resilient metal base portion enclosed therein, formed of a single plate substantially in the shape of the pad and extending nearly to the edge thereof, said base portion being provided with two integrally formed branches bent toward each other from the outer edges of said plate in contact therewith thruout their length within said plastie, and extending outwardly therefrom to form arms resting parallel in contact with each other thruout their length and being adapted to fit in a slot of corresponding form and when the ends thereof are spaced from each other to hold said device in position with relation to said opening and prevent rotational movement therein, said plastic covering completely enclosing said metal base portion, and in the rear of the pad extending to the junction of the outwardly extending parallel arms.

2. A construction as defined in claim 1, in which said arms are adapted to fit closely in a rectangular opening.

3. A construction as defined in claim 1, in

which said arms provide thin flat spreading prongs when spaced from each other.

4. A pad construction for eyeglasses comprising a plastic body pad portion, a non-resilient metal base portion enclosed therein, formed of a single plate, said base portion being provided with two integrally formed branches bent toward each other from the outer edges of said plate in contact therewith thruout their length within said plastic, and extending outwardly therefrom to form arms resting parallel in contact with each other thruout their length and being adapted to fit in a slot of corresponding form and when the ends thereof are spaced from each other to hold said device in position with relation to said opening and prevent rotational movement therein, said plastic covering completely enclosing said metal base portion, and in the rear of the pad extending to the junction of the outwardly extending parallel arms, and said arms being adapted for further spreading from the surface of said base portion to accommodate the device to a widening of said opening due to wearing of the edges thereof.
